Toyota Avalon 2008-2010



  • I would like to see bluetooth as well. Heated rear seats would be nice since you feel bad for the kids on those cold winter days when your tail is warm and they are complaining.

    I think that a smoother shifting, less quirky transmission would be nice in 08.

    maybe the thing that I wouldn't like to see in the 08 - an updated 6 speed tranny as in the Camry or ES.

    If Honda can give away an XM radio free trial with the EX, Toyota can give it away with the Avalon. And standard Bluetooth, even though I no personal need for it. The fuel screens on the NAV need a major improvement as they are almost worthless.

    Larger seat bottoms would be nice (back to the '03 seat width and depth) and a little work on the transmission to make it like the LS 460 - 8 forward gears - slick as glass.

    Well...we can dream....... :)

    athough I know of no reported problems with the 8 speed in the LS, I can't imagine that, given Toyota/Lexus' recent drivability issues with auto trannies, the 8 speed would be any better than the current 5 speed. The only thing I could see it adding is some additional repair costs. As far as Toyota is concerned, history would seem to indicate that LESS is BETTER, and the engine is such that it doesn't need the extra gears?

    All things considered with the Avalons, less seems to be a lot better. You're right. In reality, there simply must be a way to fix this 5 speed transmission to act as the old 4 speeds did... smoooothe. It can't be that hard, can it? CE's and EE's can redo anything at the speed of light. Be optimistic that Toyota will resolve this issue slowly and it will ultimately become a non-event. They have 5 months till the '08 is due...

    remembering that the 6 speed is continuing to create more problems with Camry and ES owners than I think the 5 speed ever created with the Avalon? I believe the 6 speed is destined for the 08 Avalon if for no other reason than mfrg. efficiencies...

    I have to agree with you again. The 4 speed, while antiquated somewhat has never given me any problems. The only complaint that I could possibly give is that OD gear is long, and when driving around a city or 45MPH area, it will hunt, excessively for me. soo. I just push the OD off button and cut out the 4th gear. Other than that, the shifts at 88K are still smooth, especially if you let off on the accelerator slightly at the shift points. If you push the car, you obviously can feel the shifts more.

    All in all though, no problems, and have changed the fluid twice and filter once in 88K. Sometimes less is more.

    I agree completely, the second generation Avalon interior was (is) classy with the faux wood trim. If they can duplicate that on the 2008 or the next generation Toyota would have have that market segment (50+) to itself.

    For me to buy it'll need 2 things: 1) Ipod connection port and 2) Bluetooth. It's so strange that the Avalon doesn't offer these 21st centry "musts".

    not so sure - would bet that VSC becomes standard on the 08 - which sounds unrelated except that you have to have all the silly DBW stuff for the VSC to work...
  • wwestwwest Posts: 10,706
    Sorry, the DBW has absolutely nothing to do with VSC. My 2001 AWD RX300 has VSC/Trac/etc, with a SOLID cable between the gas pedal and throttle butterfly.

    Toyota adopted the DBW system to "protect the drive train", delay the onset of engine accelerating torque until a sequential downshift, following a full lift-throttle upshift, would be completed before the onset of engine torque rising.

    Not that other uses aren't made of DBW now that its there.
  • captain2captain2 Posts: 3,971
    indirectly wwest, I'll contend it does - how else can these mfgrs. provide VSC to the consumers (and governmental agencies) that want it - without electronic (and computer)control of the accelerator, brakes, tranny etc., a contention you seem to later acknowledge in your post. What came first 'the chicken or the egg' now that I don't know.
  • wwestwwest Posts: 10,706
    Maybe you're confusing VSC functionality with TC, Traction Control functionality. With TC on a FWD if a wheel begins to slip/spin due to engine torque both front brakes will be applied moderately and at the same time the engine will be dethrottled. On a RWD engine dethrottling may be delayed to give the driver time to "feather" the throttle in reaction to the wheelspin/slip. Prior to DBW engine dethrottling was accomplished via fuel cut through the injectors.

    The brakes are used mostly for implementation of VSC functionality. Outside front brake for overstearing and inside rear brake for understearing. I suppose dethrottling the engine, especially with understearing, might be helpful, but again that can be accomplished via fuel cut.

    Obviously with DBW available it would be best to cut both intake airflow and fuel.
  • captain2captain2 Posts: 3,971
    no confusion, to use something a little more Biblical - one 'begets' the other, once those DBW systems in place it is amazing how these computer nerds can screw up a car, what I don't understand is why the consumer even wants them?
  • wwestwwest Posts: 10,706
    "..why the consumer even wants them..."

    My 2001 Porsche 911/996 C4 has DBW and I have absolutely no complaints.

    The real problem is that Toyota/Lexus adopted the DBW system as a fix, solution, for another problem that seemingly could not be solved otherwise. They adopted the automatic transaxle upshift technique back at the beginning of the RX production run and that resulted in premature transaxle failures for those models.

    But the most obvious solution would have been to redesign the transaxle with a variable displacement ATF oil pump as Ford has done but that really is a major redesign whereas adopting the DBW system is relatively simple.

    And then asking those computer nerds to throw in a 2-3 second throttle opening delay while the transaxle is downshifting to the more appropreate gear ratios is another simple matter.

    Acetylene headlights metamorphosed to electricity, sealed beams, halogen, HID versions; brakes from two-wheel, contracting, to four-wheel expanding, front-disk/rear-drum, all-wheel disk; aircraft from fabric to aluminum, titanium, fly-by-wire.
    Without such progress, the possibility of a 270-horsepower, two-ton vehicle travelling above 70mph while attaining over 30 mpg, would be unlikely. It seems clear that most consumers prefer the fruits of invention. The decades-old Crown Victoria design is being remaindered while its maker flounders toward the future with too little, too late. Some stumbles by manufacturers trying too much or too soon are less likely to be fatal to the organization.
  • captain2captain2 Posts: 3,971
    no argument here, I drive a wonderful 05 Av Touring, get 27 mpg overall, and still have power that rivals most of those 60-70s 'muscle cars'. It is somewhat contradictory, loving those parts of this technology that serve my purpose, and loathing that part that doesn't.

    you're sure that is not more like - hey, these 'safety' systems sell like hotcakes, the government will be requiring them shortly anyway, so let's put in the DBW and then, we can address things like TS and engine braking issues more easily? Chicken or the egg.
    Nissans were selling just fine at the time of the RX intro with hellatious TS and correspondent engine braking issues without the DBW. Don't perceive that either the consumer or even the 'safety' nuts thought it was that much of a problem at the time (say 2002-03). The new Maximas/Altimas, though, this has 'disappeared' into electronic never-never land in combination with that CVT.
  • wwestwwest Posts: 10,706
    It's not that I don't agree you, at least partially, but the fact of the matter is that Toyota/Lexus has not yet fully solved the FWD transaxle problem even using DBW to delay the onset of engine torque when the accelerator pedal is depressed shortly after a FULL lift-throttle coastdown event.

    The other issue is from an emissions startpoint, government, EPA, CARB, regulations. Using the SFI system to cut fuel and thereby reduce engine torque to accommodate these so called safety systems, VSC/Trac/BA/EBD/ABS/etc, was undoubtedly the most inexpensive method of accomplishing that task.

    But simply reducing the fuel flow but not closing the throttle to reduce airflow would quite certainly get the attention of those agencies.

    But, in your favor, totally, if the issue of engine RPM matching to road speed to reduce engine compression braking in the new Suzuki SX4 with manual transaxle is actually true then clearly a DBW system was required for that.

    Toyota has Bluetooth capabilities on many of its car, just not the Avalon. Why not?
    The 3.5 engine is fantastic in power and gas mileage. I am glad to see Toyota using it also in the Camry, Rav-4, Sienna and Highlander for 2008.
    Not everybody likes having a sunroof, so hopefuuly one day they will offer more solid hardtops.
    Happy Toyotering!
